FOR ALL YOU VIRUS SCANNER USERS OUT THERE!
When doing a Scan, do so in Safe Mode. You will literally find 65% more viruses on your system in safe mode. Antivirus will scan everything but cant necessaryily change everything while windows is in normal mode, simply because they are services running the virus, and windows cant do squat about it.
In Safe mode you do a scan and you get a complete virus scan, and you will find more trojan's and bug viruses then normal.
In Windows XP, to boot to safe mode, restart your computer and when the DOS screen comes up hold F8 until you prompted to select a boot option, choose safe mode.
Before doing so ensure you have the latest security threats from norton installed.
Do the scan, and do it as thorough as norton can get.
I did a scan on my HDD's in normal mode, found no bugs or viruses, did a scan in Safe mode, found 1000+ viruses and bugs running as services in Windows XP.
I now do a scan in safe mode once a week to ensure im secure, as well as running a firewall 24/7.
Oh and stop visiting porn sites, thats where you get the viruses, darn pron freaks.
